Abstract (en)
[origin: EP2886373A2] A self-inflating tire (12) is disclosed having a tire cavity (40), first and second sidewalls (15) extending respectively from first and second tire bead regions to a tire tread region and a first and second air passageway (43, 44) each having an inlet end (42, 48) and an outlet end (46, 52), each air passageway outlet end (46, 52) being in fluid communication with the tire cavity (40). The tire (12) further comprises a regulator device (300) having a regulator body (310) having an interior chamber (320) and a pressure membrane (550) mounted on the regulator device (300). The regulator body (310) has a first, second and third, preferably flexible duct (350, 360, 370), wherein the first, second and third ducts (350, 360, 370) each have an internal passageway (352, 362, 372), wherein the third, preferably flexible duct (370) has a first end in fluid communication with the outside air and a second end in fluid communication with the interior chamber (320) of the regulator device (300), wherein the first, preferably flexible duct (350) has a first end (354) in fluid communication with the inlet end (42) of the first air passageway (43), and a second end in fluid communication with the outlet port (330) of the regulator device (300), and wherein the second, preferably flexible duct (370) has a first end in fluid communication with the inlet end (48) of the second air passageway (44) and a second end in fluid communication with the outlet port (330) of the regulator device (300).
